Slow internet after 16:00

Telkom amazes me in terms of that they can replace and upgrade the exchange but still deliver poor products and services.<br> <br> i have complained many times but to a deaf ear or the buck gets passed on.<br> <br> Everyday from 16:00 to 12:00 or later there is high latency high ping just a poor internet experience.<br> i am on 4mb line 50gb of data..<br> <br> IT has to be exchange that cannot handle the amount of people , they want to install FTTH in the area up the road from me but they wont bother fixing the issue at the exchange.
